Joe I had asked on two other sites besides this one, no one came up with having had two dyno's done on the same engine with both MWs and aftermarket, but the general concensus was as high as 60-90 HP, which I felt was to much to give up. I had done a bunch of web searching, only thing that I could find was the fact that clear back in 63, the big mopar racers were replacing the cast iron headers with 4 tube aftermarket headers. I had priced the tti, and by the time you had a set that was coated, you were at the price of the repopped original cast iron ones, doing some more searching, I found that hedman had their elite series, which has a 3/8 flange, and is made from 14 gauge tubing which is heavier than most of the others on the market, as well as being ceramic coated for only $309. thru summit racing, as well as they are actually listed to fit our cars. I would still like to see some actual dyno results, but I did gather enough info that it change my mind, the idea of paying an extra $500, and ending up with even 50 hp less, just blew the WOW factor down the drain , , , dodger [Non-text portions of this message have been removed] ---- Please address private mail -- mail of interest to only one person -- directly to that person.
